e5ce30fed8 Clean up init /proc/cmdline handling.
Helped debug a problem where the N9 bootloader incorrectly
concatenated the various command lines.

f667a3247a init: get rid of the remaining double mounts
Don't double mount /dev and its subdirectories anymore. Instead, the
first stage init is solely responsible for mounting it.

Don't have init prepare the property space. This is the responsibility
of the second stage init.

Don't have SELinux use the property space to determine how we should
be running. Instead, create a new function and extract the data we
need directly from /proc/cmdline. SELinux needs this information in
the first stage init process where the property service isn't available.

da40c00137 Log more timing information from init.
Also make important events in init's life NOTICE rather than INFO,
and ensure that NOTICE events actually make it to the kernel log.

Also fix the logging so that if you have a printf format string
error, the compiler now catches it.

Also give messages from init, ueventd, and watchdogd distinct tags.
(Previously they'd all call themselves "init", and dmesg doesn't
include pids, so you couldn't untangle them.)

Also include the tag in SELinux messages.

74b34f3cb7 Remove /proc/cpuinfo parsing
- Clean up the paths for ro.revision and ro.hardware parsing
- Use ro.hardwre in ueventd instead of parsing the kernel command line

(cherry-pick of 38b340a52f8e864650db8bae1eb88d5c00485db0.)

f682b4786a Clean up reading and writing in init.
This isn't particularly useful in and of itself, but it does introduce the
first (trivial) unit test, improves the documentation (including details
about how to debug init crashes), and made me aware of how unpleasant the
existing parser is.

I also fixed a bug in passing --- unless you thought the "peboot" and "pm"
commands were features...

a016c42b4f Init: Remove unused variables
For build-system CFLAGS clean-up, fix unused variables.

Use a #define instead of static variable in a header file.

8348d279c7 Add support for socket security context specification.
Add an optional argument to the socket option for specifying
a SELinux security context for the socket.  Normally the socket
security context is automatically computed from the service security
context or set using the seclabel option, but this facility allows
dealing with two scenarios that cannot be addressed using the existing
mechanisms:
1) Use of logwrapper to wrap a service.
In this case, init cannot determine the service security context
as it does not directly execute it and we do not want logwrapper
to run in the same domain as the service.

2) Situations where a service has multiple sockets and we want to
label them distinctly.

e096e36e50 Set the SELinux security label on new directories.
Automatically set the SELinux security label on directories created
by init.rc.  This avoids the need to separately call restorecon on
each such directory from the init.rc file.  Also restorecon /dev
and /dev/socket after initial policy load so that they are labeled
correctly before any other dev nodes or sockets are created.

2b99543cef Pick up on androidboot.hardware kernel cmd option
x86 emulator passes hardware name through the androidboot.hardware kernel cmd option, and
ueventd must pick up on it to locate proper ueventd.rc file for that hardware.

b0ab94b7d5 init: create symlinks to block device nodes
eMMC block device names may change based on the detection order of
the eMMC device and any other SD bus devices, such as a removable SD
card.

This patch adds support to init for:
  * Symlinks to block devices.  When a block device uevent is
    processed, if it starts with "/devices/platform", the platform
    driver name is parsed out, and symlinks to the block device are
    created in /dev/block/platform/<platform driver>/
  * Symlinks based on partition name and number.  If the uevent for
    a block device contains information on the partition name or
    number, symlinks are created under
    /dev/block/platform/<platform driver>/by-num/p<partition>
    and
    /dev/block/platform/<platform driver>/by-name/<partition name>

init.rc can then use a device path like the following to mount an
eMMC device:
/dev/block/platform/<platform>/by-name/system /system ro
